Abstract

The utility model relates to a hollow reverse burner for coal stoves, which is composed of a grate, a stove plate, a coal collecting basin, a fire guide cage, etc. The utility model has the characteristics that the hollow reverse burner for coal stoves has quick ignition, black dense smoke pollution is eliminated, coal smoke gas energy is exploited and utilized, and the heating quantity of coal is increased in multiples; after coal is once filled, various fire utilization conditions can be arbitrarily regulated for many times in a repeated mode at any time, fire is effectively concentrated, and heat utilization rate during cooking or warming is increased; the hollow reverse burner for coal stoves is suitable for all kinds of coal, manufacture cost is low, the hollow reverse burner for coal stoves is suitable for the reformation of various coal stoves, installation and use are convenient, etc.

Description

Hollow reverse burner for coal stove

The hollow back fire device of coal stove that a kind of various coal stove is general.

Various burner hearths in the past and moulded coal burner hearth inside, the design form that it is traditional makes burning of coal all carry out from bottom to top.The coal combustion process that this traditional chamber design form forms, because not coal-fired the adding in the stove, before its combustion heating, be subjected to the coal-fired high temperature action of lower floor earlier, not coal-fired in addition skin temperature and lack of air, unburned coal gas and dense smoke and heating are just discharged, both wasted fire coal, again contaminated environment.In addition, traditional chamber design form makes with the situation of fire also undesirable.The very hot oven time is short, needs frequent coal banking fire, and coal-fired waste is very big.

Economize on coal and antipollution problem in order to solve, the various air inlets of improvement, outlet flue flashboard were once arranged, regulated flue gas flow, various designs such as control burning speed, but all the end solves stoking banking fire,, and dense smoke, the coal gas fully burning basic problems such as energy dissipation of just discharging uneven with fire.

The purpose of this utility model, be according to the anti-theory of burning in coal seam, by the new-type structure Design of burner hearth, solve dense smoke, coal gas and do not reach burning and produce heat and just discharge and promptly waste and pollution problems, make it have characteristics balanced with fire, sufficient combustion with the energy of abundant development and use dense smoke, coal gas.

Fig. 1. be principle schematic of the present utility model, Fig. 2 is an embodiment principle schematic of the present utility model, and Fig. 3 is fire-regulating ring, fire regulating cover schematic diagram.Each label is respectively that 1 Bi Zi, 2 coal holding pots, 3 fire guiding baskets, 4 transfer fire dishes, 5 fire-regulating rings, 6 fire regulating covers, 7 bells, 8 stove circles, 9 stone or metal plate for standing a stove on as a precaution against fires, 10 discharge flues, 11 burner hearths, 12 bodies of heater, 13 to take pawl, 14 supporting legs, 15 connecting rings, 16 stove legs, 17 cage bars among the figure.

Show such as Fig. 1, the utility model is taken the interior lower end that pawl 13 is overlapped on coal holding pot 2 by Bi Zi 1 usefulness, coal holding pot 2 is inverted trapezoidal, big mouthful upwards, fire guiding basket 3 arranges supporting leg according to circle 3 sides' 4 principle, and is supported on by supporting leg on the Da Kou limit of coal holding pot 2, and the diameter of fire guiding basket 3 is less than the osculum diameter of coal holding pot 2, highly be the 2-4 of diameter doubly, transfer fire dish 4, fire-regulating ring 5, fire regulating cover 6 to mount cover above fire guiding basket 3.

Bi Zi 1 can be at any time freely takes out and packs into or the opening that overturns from end opening under the situation that does not influence burning, and in order to removing slag and ashes, size is as the criterion greater than pulling out coal basin 2 osculum diameters to take pawl 13 diameters;

Coal holding pot 2 is vertebra shape tubbiness parts, with various burner hearth different shapes is set, a big mouthful diameter is as the criterion to be slightly smaller than corresponding furnace diameter, the osculum area is the 25-60% of big open area, two open height differences are 30-80mm, can play and draw remaining stove fire in, concentrate air port, preheated air, make that residual coal is grilled thoroughly, the effect of support carbon fire bed, supporting fire guiding basket.

Fire guiding basket 3 diameters are 30-150mm, with highly different and different.Fire guiding basket 3 highly is between the 100-300mm.Cage bar 17 two ends connect to tubbiness by connecting ring 15.Usually burner hearth is big, the thick fire guiding basket 3 corresponding just height, thick in coal seam.The radical of retaining coal cage bar 17 is decided with fire guiding basket 3 diameter, is spaced apart 10-30mm usually.The upper end of fire guiding basket 3 should be lower than transfers fire dish 410-20mm.The effect of fire guiding basket is in can guiding, the heat of lower floor's fire and preheated air burn the upper strata along the cage heart, forms drawing fires, ventilation and anti-burning state from center to periphery.

Transfer fire dish 4, fire-regulating ring 5, fire regulating cover 6 to be used for regulating with fire amount and coal consumption.Transfer fire dish 4 to be divided into different shapes such as square, round as required with shape, endoporus cooperates for circular with fire-regulating ring, and specification will be slightly smaller than upper strata stone or metal plate for standing a stove on as a precaution against fire endoporus.Fire-regulating ring 5 and fire regulating cover 6 are shown the triangle hole shape as Fig. 3 and cooperate, and mobile fire regulating cover 6 can be regulated with fire amount and coal consumption with the openings of sizes of fire-regulating ring delthyrium.Transferring fire dish 4, fire-regulating ring 5, fire regulating cover 6 to be installed in stone or metal plate for standing a stove on as a precaution against fire 9 following about 50mm places that Fig. 2 shows, is discharge flue 10 therebetween.

The course of work of the present utility model is as follows, coal-fired burning around coal holding pot 2 and fire guiding basket 3, after the coal-fired fully burning, part ashes can directly appear from Bi Zi 1, the lime-ash of bulk then can draw off by opening Bi Zi 1, ember draws in and concentrates in the coal holding pot 2, below the fire guiding basket 3, new coal from suitable for reading join fire guiding basket 3 around, stove fire connects by transferring fire dish and discharge flue 10 along fire guiding basket 3, it is burnt away, have heat to be defeated by the upper strata of new stoking simultaneously, for it connects for clean-burning temperature and air.

The utility model is because reasonable in design, simple in structure, so have quick combustion, eliminate black smoke pollution and development and use coal smoke gas energy, significantly improve the caloric value of coal, can at any time, arbitrarily, repeatedly regulate the fiery situation of various usefulness, active set moderate heat amount behind coal repeatedly, the heat utilization efficiency when improving cooking or heating, do not choose coal, low cost of manufacture, be fit to various coal stove transformations, characteristics such as easy to install.
